NCT ID NCT06192966
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested a daily probiotic supplement containing Lactobacillus plantarum, cranberry, and vitamin C to see if it could prevent recurrent urinary tract infections (UTIs) in women. The trial planned to enroll 106 women with a history of frequent UTIs, but it was terminated early. Researchers aimed to measure how many women had another UTI and how long they stayed infection-free.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Probiotic supplement with Lactobacillus plantarum, cranberry, and vitamin C
What this could lead to
If it worked, this supplement could help reduce the number of repeat urinary tract infections in women, offering a non-antibiotic option.
What could go wrong
The trial was terminated early, so results are limited. It was a small study, and supplements are not as strictly regulated as drugs, so effectiveness is uncertain.
